OBJECTIVE To invstigate the diagnosis role of VEMP for inferior vestibular neuritis. METHODS 18 patients with inferior vestibular neuritis were studied. Especially, the oVEMP and cVEMP were recorded in all cases. RESULTS All 18 patients with VN (vertigo symptom in 15 cases, and balance disorders in 3 cases) presented normal in PTA, caloric test and Ovemp test. By contrast, the cVEMPs was abnormal in all patients with VN, including flat/no amplitude of cVEMP in 14 cases, and lower amplitude in 4 cases. After three months, 10 patients recovered, with nomal amplitude of cVEMP in 9 cases and lower amplitude in 1 case. And after half-a-year-follow-up, 18 patients went back to normal, with lower amplitude in only 2 cases. CONCLUSION The VEMP examination is valuable in the diagnosis and prognosis of inferior vestibular neuritis.

The conventional total arch replacement (cTAR) with frozen elephant trunk implantation is commonly regarded as the gold standard for aortic pathologies involving ascending aorta and proximal aortic arch. By combining open supra-aortic vessels debranching and emerging endovascular technologies, hybrid arch repair (HAR) has been increasingly performed as a promising alternative in risky patients with comorbidities and frailties. Nevertheless, the advantages or disadvantages of hybrid arch procedures and cTAR in terms of survival and related outcomes remain controversial. This study is aimed to briefly review the role and results of HAR in the management of aortic arch pathology in comparison of contemporary cTAR.
